09.09.2020 · This python code can solve one non- coupled differential equation: import numpy as np import matplotlib.pyplot as plt import numba import time start_time = time.clock() @numba.jit() # A sample differential equation "dy / dx = (x - y**2)/2" def dydx(x, y): return ((x - y**2)/2) # Finds value of y for a given x using step size h # and initial value y0 at x0.
28.01.2020 · The first step is to transform the second order equation to a set of two coupled first order equations. Define an auxiliary function u ( T) = d r ( T) d T. This results in the system d u d T = k − ( 1 − 5 r) ( 3 + 2 r 2) d r d T = u d ϕ d T = 1 r 2 Now you have a set of three coupled first order equations in the form fit for solving with solve_ivp.
